REVOLVING WINDOW-FRAME.

Specification of Letters Patent.

Patented Jul 13,1920.

Application filed March 14, 1919. Serial No. 282,606.

To all whom it may concern:

1 Frames, of which the following is a specification.

The purpose of the invention is to provide a new and improved construction of window frame so supported with the frame that it may-be turned around to bring that side which is normally outside into such a position that the panes in the frame may readily have 'their outside faces cleaned from within the room. The improved frame is also useful as a means for opening a window of which it is a part so that the benefit of the full window opening may be had for ventilation in times of warm weather.

A further purpose of the invention is the provision of a device of this character which is simple in construction, durable and effective in operation and inexpensive to manufacture and apply.

Other and further objects appear in the following description, wherein the invention is set forth in detail.

To the exact construction in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations 'are compatible in spirit with the annexed claim. A

In the accompanying drawings:

Figure 1 is a front elevational view of the improved window frame.

Fig. 2 is a section on the line 2-2 of Fig. 1. '7

Fig. 3 is a section on the line 33 of Fi 1.

iig. 4 is a detailed perspective view showing a portion of the frame and the pivot stud therefor.

Fig. 5 is a detailed elevational view showing one of the slides by means of which the frame is secured in its normal position.

To carry the invention into effect there is provided a main frame 1 for the window opening, this frame having the usual verti cal stiles and resting upon the sill 2.

A transverse plate member 3 is attached on the inner or underface of the top of the frame 1, and set centrally both as respects the sill at which time its under the length and widthcf this plate there is a socket member 4, this socket member being set in the plate so that its bottom lies flush with the bottom face of the plate. Set in the sill 2 and directly below the socket 4 there is a second socket 5 and these two sockets are designed to receive the studs 6 which project from and are formed with plates 7, the

latter being set in the top and bottom edges of a supplemental frame 8, the latter being formed with appropriate beads 9 so that it may receive the sash 10, this supplemental frame being pocketed on its sides for the reception of the sash controlling means, which may be either weights connected with the sash by appropriate chains or ropes, or spring operated rollers as indicated at 11 which are connected to the sash by appropriate chains as indicated at 12. Any appropriate means of mounting the sash may be employed, such means being no part of the present invention, and hence'needless ofdetailed description here.

By virtue of the studs 6, however, the supplemental frame .8 which carries a sash maybe rotated in the main frame 1 to bring those sides of the sash normally'outside to a' position where they stand facing the inside of the room. The sash-may thus be easily cleaned when the supplemental frame 8 is turned around.

In the normal position of the supplemental frame, however, means are provided for looking it in such a position as well as for keeping out drafts through the cracks existing between it and the main frame thereto, and to this end there is attached to a plate 13 which is secured to the main frame by means of the hinges 14, this plate normally lying against the inner edge of the plate 3 and agalnst the inside face of the supplemental frame at the top thereof. Likewise, at the bottom ends a second plate, this plate generally designated 15 is secured to the sill 2 by means of the hinges 16 and this plate, therefore, may swing over to have its under face lie on top of the sill with-its edge against the inner face of the supplemental frame 8 at the bottom thereof. The plate 15 may'also be swung back awa from ace is brought into a plane parallel to a plane of the top face of the sill, in which position of the plate 15 the supplemental frame 8 may the ,underfaceof the top of the main frame be turned around, such movement of the frame 8 causing the plate 13 to be swung back towarda horizontal ition to permit the frame 8 to pass 11 the plate 15, however, is turned over to bring its edge against the inner face of the frame 8 turnin movement of the latter is precluded.

n addition to providing the plate 15 to secure the frame 8 against movement, means "main frame 1, or moved laterally in the re- 4 .8 may 17 and they may be moved laterally to engage in slots formed in the sides of the verse direction to disengage them from the said slots, so that when the plate 15 is turned as aforesaid, the supplemental frame be turned freel slots 18 are disposed so t at when the plates 17 are moved laterally the are likewise -moved upwardly and comblned clamping screws and handles 20 are threadingly mounted in these plates so that they may be easily moved by hand, and clamped in the.

positions to which they are moved, the tightening of the clamping screws 20 serving to thereof and lying normall The transverse seat them against the iniier face of the frame 8, to hold the .lates 17 in any position to which they may e moved.

From the foregoing description and the accompanyin drawings, it is believed that a clear enoug understanding of the invention is to be had to render further description unnecessary.

The invention having been described, wha is, claimed as new and useful is;

A revolving window frame comprising a main frame, a supplemental frame support on vertical pivots for turning movements in the main frame, a plate swingingly mounted at the top of the main frame and avity actuated to "lie against the window ace of thereof whereby it ma swing out of the wayof the 'supplementa frame on the turn-' ing of the latter, a second plate hingedly attached'to the main frame at the bottom horizontal to have its free edge engage t e supplemental frame at the bottom thereof whereby turnu ing movement of the supplemental frame is precluded exce t on raising the said plate to swing outwar ly and upwardly from the main frame, and lateral movable plates mounted on the supplemental frame and en-" gageable with side slotsin the main frame, in the manner and for the purpose specified. In testimony whereof I aflix my si nature.
